File locking and unlocking method and system

Abstract

The invention provides a file locking method and system which achieve the purpose that a file is automatically locked when the file is edited by multiple users in a cooperation mode. The system comprises a state detection device, a state synchronizing device and a far end server. The file locking method is based on events, when the file is opened and edited, a certain system event is generated, the state detection device judges the locking state of the file after the corresponding event is received, the state synchronizing device synchronizes the locking state to the far end server, the far end server synchronizes the state to devices of other users, and the state synchronizing devices on the devices of other users update the local file information.

Description

technical field [0001] The invention relates to an event-based file locking and unlocking method and system. Background technique [0002] In today's file processing process, especially in the office process, it is quite common for multiple people to edit files collaboratively. However, since the users involved in editing the file are operating on their own computers, it is difficult to determine whether the file is being edited by another user while it is being edited, or whether it has been edited by another user before it is completed A new version of the file was created. In this case, it is easy to cause content conflicts in the same file, and may even cause the content edited by the user to be lost or overwritten by other data, thereby causing certain losses. [0003] The solution to this problem is to lock the edited file when the user edits the file, thereby denying other people the possibility of modifying the edited file. The commonly used method at present is t...

AI Technical Summary

Problems solved by technology

First, the method of manually locking and unlocking files is very cumbersome. For collaborative editing users, it is also necessary to agree on when to lock files and when to unlock files

Second, when multiple files need to be edited or some programs need to automatically modify some files, manual locking and unlocking will greatly reduce the efficiency of file processing, and users cannot lock and unlock files correctly and effectively

Third, if the user forgets to unlock the file, or if the user encounters a system crash, program error, etc. during the process of editing the file after locking the file, the user may not be able to unlock the file in time, and other users will not be able to edit the file, which will bring losses to the entire team
